不用杨氏方程预测内禀Wedge

The Prediction of Intrinsic Wettability without Young's Equation

Haohao Gu, Hao Wang

摘要:

本文采用绝对光滑表面和晶格结构表面来区分不同液固组合的本征润湿性与颗粒间微观作用的关系。采用绝对光滑表面有利于消除任何特定的表面特征,从而使人们能够在液-液凝聚力和液-固粘附力之间的竞争表示的基础上了解固有润湿性的确定。晶格结构的引入进一步揭示了涉及各种界面性质的可能性,并表明现实表面的复杂特征(拓扑结构或化学组成)可能会对固-流能量比与接触角之间的线性关系引入某种偏差。在目前的工作中介绍的方法的预测潜力需要更多的确认,但它确实提供了一个可能的杨氏方程的解决方案来预测接触角。

英文摘要:

The current work employed absolutely smooth surface and lattice structure surface to distinguish the relationship between intrinsic wettability of different combinations of liquid and solid particles and the microscopic interparticle actions. The adopting of absolute smooth surface facilitates the eliminating of any specific surface characteristics and consequently give an insight into the determination of intrinsic wettability on the foundation of the express of competition between liquid-liquid cohesion force and liquid-solid adhesion force. Further the introduction of lattice structure reveals the possibility of involving various interfacial properties, and indicate that the complex characteristics of realistic surfaces (either topology or chemical composition) may introduce some kind of deviation to the linear relationship between solid-fluid energy ratio and contact angle. The prediction potential of the method introduced in present work need more confirmation, but it does provide a possible Young's-equation-free solution to predict contact angle.
